With OpenStack being the orchestrater running on top of Ubuntu, you can run any appliance or VM you desire as long as they are imported as KVM images. If you’d like some topologies contains some pre-baked topologies to get you going.

And if you get your head round it, the annual Personal Edition license becomes less onerous, running it on your own tin or on Packet.

If you’ve already got a Cisco CCO account you’re already able to access DevNet with that. All you need to do is register with Cisco DevNet. Cisco VIRL is available on Cisco DevNet – FREE. VIRL does have a learning curve which is slightly higher than GNS3 and is also has pay-for annual license. Aswell as the long standing API, HTML and CLI operations are now possible. There’s no need to use VM Maestro any more. Since then, the VIRL team have ironed out some big criticisms. It had a bad reputation and still carries that with it.

I tried out Cisco VIRL a few years back and I wasn’t bought into it. Physical is definitely the least good option here. In an age where a great deal of our world is virtualised, I’ve little appetite for going through months of eBay purchases of routers, switches and ancillary devices again. That being said, once it was setup, the INE CCIE workbooks made it great to operate. It’s costly – even when buying second hand, requires its own troubleshooting, power and space. I’ve owned a physical lab in the past for my original CCNA and CCNP exams. There’s a few choices to be made in 2019 for working with your lab The Lab for the Route exam will be everything. With that in mind, I’m not going to commit to booking the exam until July 2019 and whatever is the current version of the CCNP Layer 3 exam, then, I’ll commit to taking in September 2019. I’m also concious it’s 2019 and the Route 300-101 has been around for quite some time. Given I currently work least with routing protocols, the Route 300-101 feels like a really good choice for me and I’m really looking forward the challenge rather than working with relatively familiar Layer 2 technologies.

I deal with Layer 3 the least on a day to day basis.

Out of all the 300-xxx exams, I’ve chosen the Route 300-101 exam because

I’ve chosen to re-certify my Cisco Professional level certifications to maintain an employment advantage. It seems a chap has found his own way of running Docker without requiring Hyper-V, but using VMware Workstation. So, it seems the GNS3 VM running on the same host – at distance – as the host that I’ve got for VIRL seems like the right ticket. THEN – I find that Hyper-V (enabled for Docker Desktop) and VMware Workstation for running the GNS3 VM are mutually exclusive. So, to facilitate using Frame Relay, I’ve had to back out to GNS3. Now, spending time with VIRL, VIRL is not able to do Frame Relay interfaces which is miserable in itself as who uses Frame Relay anyways. This should leave you with an ASA with the call-home feature disabled and no alerts generated by the device. Once you’ve removed that, then you can disable call-home and reporting and finally do a clear configure on call-home.

To remove the certificate, use the serial number that matches yours at the end of the above message to complete the below commands – for me “6ecc7aa5a7032009b8cebcf4e952d491” is the correct choice.Ĭrypto ca certificate chain _SmartCallHome_ServerCA Simply, I’ve no interest in maintaining this construct and feature. Expiration Subject Name Issuer Name Serial Number The message manifests into your inbox with the following text Ġ7:48:28 UKHQFW01: %ASA-1-717055: The certificate in the trustpoint has expired. It’s a vital device in your infrastructure and numbing your responses to its messages is an undesirable outcome. You can imagine how pleasing it is then to have your ASA alert you weekly in the run up to an expiry and daily on the expiration of a call-home certificate. Either through contractual commitment or through any support calls that I’ve placed with partners. In the time I’ve been operating Cisco ASA platforms, I’ve never needed to take advantage of the Cisco call-home feature.
